first / last visible child depends on the LayoutManager. If you are using LinearLayoutManager or GridLayoutManager, you can use

int findFirstVisibleItemPosition();
int findFirstCompletelyVisibleItemPosition();
int findLastVisibleItemPosition();
int findLastCompletelyVisibleItemPosition();

For example:

GridLayoutManager layoutManager = ((GridLayoutManager)mRecyclerView.getLayoutManager());
int firstVisiblePosition = layoutManager.findLastCompletelyVisibleItemPosition();

For LinearLayoutManager, first/last depends on the adapter ordering. Don't query children from RecyclerView; LayoutManager may be prefered to layout more items than visible for caching.

This is lot important information to me Thank you buddy to let me know about this :) — Amar Yadav, Oct 15 '15 at 06:37

You can use LayoutManager's object which you set on your recyclerView like this:

      recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
            @Override
            public void onScrolled(RecyclerView recyclerView, int dx, int dy) {

            super.onScrolled(recyclerView, dx, dy);
            int totalItems = layoutManager.getItemCount();
            int lastVisibleItem = layoutManager.findLastVisibleItemPosition();
                if (totalItems - 1 == lastVisibleItem){
                    isScrolled=0;
                    skip = skip + 5;
                            remove = 1;
                            feedItems.add(null);
                            eventsRecyclerView.notifyItemInserted(feedItems.size());
                            handler.postDelayed(new Runnable() {
                                @Override
                                public void run() {
                                    Loadmore(eventsRecyclerView,1);

                                }
                            }, 500);
                    }
            }
        });
